The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

In the Linux kernel, the following vulnerability has been resolved:
md: Fix missing release of 'active_io' for flush
submit_flushes atomic_set(&mddev->flush_pending, 1); rdev_for_each_rcu(rdev, mddev) atomic_inc(&mddev->flush_pending); bi->bi_end_io = md_end_flush submit_bio(bi); /* flush io is done first */ md_end_flush if (atomic_dec_and_test(&mddev->flush_pending)) percpu_ref_put(&mddev->active_io) -> active_io is not released
if (atomic_dec_and_test(&mddev->flush_pending)) -> missing release of active_io
For consequence, mddev_suspend() will wait for 'active_io' to be zero forever.
Fix this problem by releasing 'active_io' in submit_flushes() if 'flush_pending' is decreased to zero.
